Model confidence (pLDDT)

The mean pLDDT of this model is 48.0 (very low overall). pLDDT is AlphaFold's per-residue confidence score from 0 to 100. In MolViewer, choose the B-factor color scheme to color the model by pLDDT, because AlphaFold stores it in the B-factor column.

What pLDDT means and how to read it

Function

Probable catalytically inactive kinase. Scaffolding protein that regulates the cytoskeleton to control cell spreading and migration by modulating focal adhesion dynamics (PubMed:20534451, PubMed:23105102, PubMed:35687021). Acts as a scaffold for mediating EGFR signaling (PubMed:23846654)

Subunit structure

Homodimer (PubMed:29212708). Interacts with BCAR1 and CRK (PubMed:20534451). Interacts with PRAG1 (PubMed:29079850). Interacts (when phosphorylated at Tyr-1188) with SHC1 (via PID domain) (PubMed:23846654, PubMed:35687021). Found in a complex with PPP1CA, PPP1CC, SHC1 and PEAK1. Interacts (when phosphorylated at Tyr-635) with tensin TNS3 (when phosphorylated on the SH2 domain); TNS3 also…
